National Solar Radiation Database 1998-2014 Update
The current version of the NSRDB (v2.0.0) was developed using the Physical Solar Model (PSM), and offers users the latest available data (1998–2014). NSRDB comprises 30-minute solar and meteorological data for approximately 2 million 0.038-degree latitude by 0.038-degree longitude surface pixels (nominally 4 km2). The area covered is bordered by longitudes 25° W on the east and 175° W on the west, and by latitudes -20° S on the south and 60° N on the north.
